."BEDPOST LOCK.

Application filed January 1S, 1928. Serial No. 81,683.

My invention relates to a bedpost lock of the reversible wedge type and the object thereofl is to provide a lock which is simple and rigid in construction and can be manufactured economically.

ln the appended drawing, Figure 1 is a horizontal section on line 1-1 of Fig. 2.

Figure 2 is a vertical elevation of the lock.

Figure 3 is a perspective view of the wedge and the plate from which it is depressed.

Referring to the drawing, 5 is a tubular bedpost to which a bracket 6 is connected by means of rivets 7. The post 5 at the bracket is reinforced by a liner 8 to increase the rigidity of the bedpost tube 5 at the bracket 6.

rEhe side 9 of the bracket which extends from the tubular post has a tapering slot 1U f) open at the top as best shown by dotted lines in Figure 2.

A wedge 11 tits into slot 10. The wedge has a concave edge 12 and a convex edge 13, which are the wedging surfaces of the wedge 11. rlhe concave wedge 12 has a greater curvature than the convex edge 13; in consequence the maximum width of the wedge 11 is in the central portion thereof. As shown the wedge 11 is depressed from a plate 141, in stamping the article.

A portion l5 of the plate is off-set as best shown in Figures 1 and 3 to `be in a. plane with the wedge 11. To this off-set portion l5 and the wedge 11 is secured an angle iron 16 of a bed frame, by rivets 19 engaging suitable openings 17 and 18 in the portion 15 and the wedge respectively. As will be seen from Figure 1, the angle iron and the plate embrace the faces of the side 9 of the bracket G'when the wedge 11 is engaged into the slot l() and the bracket.

lVhen a wedge 11 is fitted into the slot 1G, it is engaged at the points a and Z) of the edge 12 and the point c of the edge 13, a three point contact is obtained.

ln addition thereto the wedge 11 is so sheared that the edges 12 and 13 taper towards the plate 14. This is obtained by giving a larger clearance to the female shearing edges ofthe die, than is customary. In consequence, in addition to being wedged along the points a, Z) and c, it is also wedged laterally, as will be best seen from Figure 1.

By forming a wedge with a concave edge and a convex edge, it is possible to use the angle iron 16 of the bed frame in two positions, either with the face thereof down as shown in Figure 1 or up, if the lock disclosed in Figure 1 would be moved to a bracket on the right side thereof. In other words, this structure gives a reversible bedpost lock.

I claim:

A bedpost lock comprising a bracket adapted to be secured to the post and having a portion thereof extending from the post, said extended portion having a tapered slot, a stamping in shape of a plate having a wedge depressed to one side thereof for engaging the slot and an olf-set port-ion to the same side as the. wedge, said wedge presenting a concave and a convex edge for engaging the slot, these edges tapering toward the plate, the cur\'fature of the concave edo'e being greater than that of the convex edge, said wedge and off-set portion having means for securing thereto an angle iron on a bed frame.
